Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
High Voltage Transformers(TR)：Transmission and ... addition to extra-high voltage (EHV) and high voltage (HV), they offer practical use of ultra-high voltage (UHV) transmission of up to 1000 kV. Along with their high level of reliability, they make use of the latest technologies such as on-site assembly and gas insulation according to transmission grid issues and applications.
SF6 gas - WIKA United Kingdom plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products.
